Hi !
Just received my 63mm X 63mm Russian eBay crystal. I am building a gamma spectrometer. I am not sure how to open and connect the crystal to a 3" PMT. How do I open the metal can the crystal is in, which end gets attached to the PMT? Any help would be appreciated. I am located in California, SF Bay Area.

DO NOT ATTEMPT TO OPEN THE METAL CAN!!!
You use the crystal as-is. Any attempt to open the can will destroy the crystal, which is VERY hygroscopic. Simply couple the window end (glass cover) of the crystal's can to your PMT using coupling grease. Then make sure the entire assembly is light tight before powering it up. That is the simple instructions, of course there is much more to it to build a nice detector, but you can find a lot of info here. Cheers, Tom
